Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of folding bed nets, and particularly relates to a bed net packaging machine for folding and packaging bed nets. BACKGROUND

[0002] The bed net is a double-layer open-bottom structure, and a loose belt is arranged at the bottom of the bed net, which results in poor flatness when the bed net is folded, and the bed net is generally not suitable for mechanical folding and packaging. Even if the bed net is folded mechanically, the bed nets can only be stacked or bagged one by one, because the final folded free form of the bed net is a triangular structure with one side up, and the upturned direction is the side of the opening after the final folding is completed. This results in that when the bed nets are stacked, the next layer will tilt and knock down the previous layer, so that the bed nets cannot be stacked. If the stacked bed nets are pressed to flatten, the stacked bed nets cannot be popped up, although the stacked bed nets can be stabilized, but when the next bed net is placed, the originally stacked bed nets will be knocked down, so the bed nets cannot be stacked.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0028] Embodiment: The present application provides a bed cover packaging machine for bed cover folding packaging, which comprises a folding conveying device 1, a flat laying platform 2, a clamping and discharging device 3, an extrusion plate 4, a bed cover pressing mechanism 5, a bed cover limiting mechanism 6, a conveying belt two 12, a lifting slide table 13, a horizontal moving slide table 14 and a mounting frame 15. Figures 1-3As shown, it comprises a folding conveying device 1, a flat laying platform 2, a clamping and discharging device 3 and a bed mat stacking and collecting device. The flat laying platform 2, the folding conveying device 1 and the clamping and discharging device 3 are arranged in sequence. First, the worker lays the bed mat on the conveying belt 2a of the flat laying platform 2. The flat laying platform 2 is provided with a conveying belt 2a for conveying the laid bed mat into the folding conveying device 1. The folding conveying device 1 is used for folding and reducing the bed mat. In order to facilitate the clamping of the clamping and discharging device 3, the opening direction of the bed mat after the last process of folding is towards the flat laying platform 2, which can ensure that the closed direction is towards the clamping and discharging device 3. Because the closed direction is an acute angle structure, the bed mat can avoid colliding with the clamping part of the clamping and discharging device 3 during conveying, ensuring the smoothness and accuracy of the conveying of the bed mat. The bed mat stacking and collecting device is used for stacking and collecting the bed mat clamped by the clamping and discharging device 3, so as to ensure that the bed mat can be stacked in multiple layers. Unlike towels or clothes, the bed mat has a double-layer structure, which causes a small amount of gas to be stored inside. These gases are difficult to discharge after folding, and even if they are squeezed out at the end, the height of the folded bed mat will also cause it to swell upwards. Therefore, there are problems in using machinery to stack and collect the bed mat.

[0029] The bed cover stacking and collecting device comprises an extrusion plate 4, a bed cover pressing mechanism 5, a downward pressing mechanism 11, a conveying belt 12, a lifting slide 13, a horizontal moving slide 14 and a mounting frame 15, the mounting frame 15 is located beside the folding conveying device 1, the clamping and discharging device 3 and the downward pressing mechanism 11 are fixedly installed on the horizontal conveying seat of the horizontal moving slide 14, the extrusion plate 4 is fixedly installed at the bottom of the downward pressing mechanism 11, the downward pressing mechanism 11 is used for pushing the extrusion plate 4 downward to extrude the bed cover 10, so that the waste gas in the bed cover 10 is discharged, the conveying belt 12 is located below the extrusion plate 4, the conveying belt 12 is used for receiving the bed cover 10 clamped and transported by the clamping and discharging device 3, the conveying belt 12 is fixedly installed on the vertical conveying seat of the lifting slide 13, the lifting slide 13 drives the conveying belt 12 to downwardly convey the thickness of one bed cover 10 every time one bed cover 10 is placed, the bed cover pressing mechanism 5 is fixedly installed on the mounting frame 15, and the bed cover pressing mechanism 5 is used for pressing and fixing the topmost bed cover 10 after the extrusion plate 4 moves away. The specific working process of the bed cover stacking and collecting device is as follows: first, the lifting slide 13 drives the conveying belt 12 to downwardly move the thickness of one bed cover 10 to be transported, the bed cover pressing mechanism 5 is installed on the mounting frame 15 and does not move with the conveying belt 12, but at this time, the bed cover pressing mechanism 5 keeps pressing the topmost bed cover 10 to be transported, because the bed cover 10 to be transported will rebound upward, and the downward movement of the thickness of one bed cover 10 will also make the topmost bed cover 10 keep in contact with the extrusion plate 4. When the bed cover 10 to be transported is clamped by the clamping and discharging device 3, the horizontal moving slide 14 drives the clamping and discharging device 3 and the downward pressing mechanism 11 to move horizontally, when the bed cover 10 to be transported moves above the pressing arm of the bed cover pressing mechanism 5, the clamping and discharging device 3 releases the clamping of the bed cover 10 to be transported, the bed cover 10 to be transported will fall on the pressing arm of the bed cover pressing mechanism 5, then the horizontal moving slide 14 is reset, so that the extrusion plate 4 moves above the bed cover 10 to be transported again, the downward pressing mechanism 11 presses the extrusion plate 4 downward, in the process of the downward pressing of the extrusion plate 4, the pressing arm of the bed cover pressing mechanism 5 is pulled out from the topmost bed cover 10 to be transported, so that the bed cover 10 to be transported rebounds upward and contacts the bed cover 10 to be transported, with the continuous downward pressing of the extrusion plate 4, all the bed covers 10 can be compressed together. After the compression is completed, the bed cover pressing mechanism 5 pushes the pressing arm to contact the topmost bed cover 10, so that all the bed covers 10 are pressed on the conveying belt 12.

[0030] In order to shorten the time of the device, the pressing mechanism 11 adopts a pressing cylinder, because the height of the pressing plate 4 is constant, the pressing cylinder can shorten the time of the pressing plate 4, and ensure the efficient movement of the device. But this will lead to the speed of the mattress pressing mechanism 5 required to move faster, and need to make a quick response in the two seconds of the movement of the pressing plate 4, and if it is controlled by electricity, it will not meet the speed requirements, and because the mattress 10 will fall above the pressing arm of the mattress pressing mechanism 5, which will cause the pressing arm to move, and the mattress 10 will move, and finally the mattress 10 will move left and right. Therefore, as shown in Figure 4 、 Figure 5 and Figure 6 , the mattress pressing mechanism 5 includes two single-sided pressing mechanisms arranged symmetrically, which are fixedly installed on the mounting frame 15, and are used to press the mattress 10 on the conveyor belt two 12. Each single-sided pressing mechanism includes a swing arm 5a, a pressing plate 5b, a synchronous outer pulling mechanism 5c, and an avoidance rotating block 5d. The tail of the swing arm 5a is rotatably installed on the mounting frame 15, the avoidance rotating block 5d is rotatably installed on the end of the swing arm 5a, the avoidance rotating block 5d cannot rotate downward, one end of the avoidance rotating block 5d is below the orthographic projection of the pressing plate 4, and the hinge of the avoidance rotating block 5d and the swing arm 5a is outside the orthographic projection of the pressing plate 4. The synchronous outer pulling mechanism 5c is fixedly installed on the mounting frame 15, and the swing arm 5a is in transmission connection with the synchronous outer pulling mechanism 5c. When the swing arm 5a rotates downward, the synchronous outer pulling mechanism 5c pulls the pressing plate 5b to move outward, the pressing plate 5b is fixedly installed on the displacement seat of the synchronous outer pulling mechanism 5c, the pressing plate 4 is provided with an avoidance notch one 4a for avoiding the avoidance rotating block 5d, and the pressing plate 4 is provided with an avoidance notch two 4d for avoiding the pressing plate 5b, so that when the pressing plate 4 presses the topmost mattress 10, the pressing plate 5b can be inserted into the avoidance notch two 4d to block the topmost mattress 10, and when the pressing plate 4 is lifted upward, the pressing plate 4 will not collide with the pressing plate 5b. The pressing plate 4 is provided with a pushing stop block 4b and an elastic pushing mechanism 4c, the pushing stop block 4b is above the avoidance notch one 4a, the pushing stop block 4b is used to abut against the avoidance rotating block 5d, the pushing stop block 4b is fixedly installed on the displacement seat of the elastic pushing mechanism 4c, the elastic pushing mechanism 4c is fixedly installed in the pressing plate 4, and the elastic pushing mechanism 4c is used to pull the pushing stop block 4b inward when the avoidance rotating block 5d cannot be pushed by the pushing stop block 4b. The pressing plate 5b is the pressing arm of the mattress pressing mechanism 5.

[0031] When the extrusion plate 4 moves downward, the end of the push block 4b is in contact with the escape rotating block 5d and continues to push, so that the swing arm 5a rotates downward, and the synchronous outward pulling mechanism 5c pulls the pressing plate 5b outward; that is, the pressing plate 5b is pulled outward, so that the pressing plate 5b releases the compression of the transported bed mat 10, and the Figure 4 As can be seen from the position of the first contact, the gap between the extrusion plate 4 and the pressing plate 5b is small, and after the pressing plate 5b is completely extracted, the gap will be smaller. The small gap can ensure that the bed mat 10 to be transported and the bed mat 10 that has been transported can be in contact with the extrusion plate 4, so as to prevent the bed mat 10 from falling over.

[0032] When the swing arm 5a cannot rotate, the pressing plate 5b is completely separated from the bed mat 10. With the continuous downward movement of the extrusion plate 4, the push block 4b is pushed inward, and the elastic pushing mechanism 4c is compressed. The distance of the buffer is to ensure that the extrusion plate 4 still has a downward distance when the pressing plate 5b is completely extracted, because when the pressing plate 5b is completely extracted, the extrusion plate 4 cannot completely compress the multi-layer bed mat 10, because the gap for extracting the pressing plate 5b needs to be reserved.

[0033] When the end of the push block 4b is separated from the top of the escape rotating block 5d, the multi-layer bed mat 10 is completely compressed, the synchronous outward pulling mechanism 5c pushes the swing arm 5a to rotate upward, and the pressing plate 5b is inserted into the top of the top layer of bed mat 10. When the escape rotating block 5d is not in contact with the push block 4b, the extrusion plate 4 also compresses the multi-layer bed mat 10 to the limit position, and the synchronous outward pulling mechanism 5c pushes the swing arm 5a to rotate by the elastic force accumulated in advance, that is, the swing arm 5a is reset, and the pressing plate 5b is inserted into the top of the bed mat 10, that is, the bed mat compression mechanism 5 again realizes the locking of the multi-layer bed mat 10. When the extrusion plate 4 moves upward subsequently, the multi-layer bed mat 10 will not move upward.

[0034] During the upward movement of the extrusion plate 4, the push block 4b will inevitably contact the escape rotating block 5d. When the push block 4b contacts the escape rotating block 5d, the push block 4b can push the escape rotating block 5d to rotate upward, that is, the escape rotating block 5d can avoid the push block 4b. After the push block 4b passes through the escape rotating block 5d, the escape rotating block 5d will be reset by gravity, and only needs to ensure that the center of gravity of the escape rotating block 5d is on the right side of the hinge. The escape rotating block 5d can only rotate downward, and only needs to set a block on the swing arm 5a to support and limit the bottom of the escape rotating block 5d.

[0035] Through the above-mentioned manner, the speed of the bed mat compression mechanism 5 can be ensured to be faster, and a quick response can be made within two seconds of the movement of the extrusion plate 4. The response process includes the quick extraction of the pressing plate 5b during the compression of the extrusion plate 4, and the quick insertion of the pressing plate 5b after the compression of the extrusion plate 4 is completed.

[0036] In order to solve the problem that the bed mat 10 to be transported will move left and right during the extraction of the pressing plate 5b, the bed mat stacking and collecting device further comprises a bed mat limiting mechanism 6, as shown in Figure 7 The bed mat limiting mechanism 6 comprises a cross pushing mechanism 6c, a guide base 6d, a connecting plate 6e, two baffle plates 6a and two guide columns 6b. The guide base 6d is fixedly installed on the mounting frame 15. The two guide columns 6b are in sliding connection with the guide base 6d. The connecting plate 6e is fixedly connected with the two guide columns 6b. The two baffle plates 6a are respectively fixedly installed on the end portions of the two guide columns 6b. The cross pushing mechanism 6c is fixedly installed on the guide base 6d. One end of the two guide columns 6b is in transmission connection with the connecting plate 6e. The other end of the cross pushing mechanism 6c is in transmission connection with the synchronous outer pulling mechanism 5c. When the pressing plate 5b is pushed outward, the cross pushing mechanism 6c will push the guide column 6b inward by the power of the synchronous outer pulling mechanism 5c. When the pressing plate 5b moves downward to the preset final position, the side surface of the baffle plate 6a is in abutment with the two sides of the two bed mats 10. When the pressing plate 5b moves, there is a probability that the folding and conveying device 1 will move left or right. At this time, in order to solve the problem, the pressing plate 5b will move, and the synchronous outer pulling mechanism 5c will move together. The synchronous outer pulling mechanism 5c will drive the cross pushing mechanism 6c to move. The cross pushing mechanism 6c will push the connecting plate 6e to move inward, so that the connecting plate 6e pushes the guide column 6b to move inward, so that the baffle plate 6a can push and position the side surface of the two bed mats 10, so that the left and right positions of the bed mat 10 can be positioned. During the movement of the pressing plate 5b, the baffle plate 6a can be pushed, because the bed mat 10 is not completely extruded by the extrusion plate 4, so that the bed mat 10 can be pushed and positioned by the baffle plate 6a.

[0037] In order to enable the pressing plate 5b to move horizontally, and enable the synchronous outer pulling mechanism 5c to move when the swing arm 5a rotates, and in order to enable the pressing plate 5b to quickly insert into the top of the multi-layer bed mat 10 after the swing arm 5a is released, the device further comprises a synchronous outer pulling mechanism 5c, as shown in Figure 7As shown, the synchronous outer pulling mechanism 5c includes guide column two 5c1, mounting plate 5c2, transmission column one 5c3, limiting connecting plate 5c4 and reset spring 5c5, the pressing plate 5b is fixedly installed on the mounting plate 5c2, one end of the guide column two 5c1 is fixedly connected with the mounting plate 5c2, the guide column two 5c1 is slidably connected with the guide base 6d, the limiting connecting plate 5c4 is fixedly installed on the guide column two 5c1, the transmission column one 5c3 is fixedly installed on the limiting connecting plate 5c4, the reset spring 5c5 is sleeved on the guide column two 5c1, the reset spring 5c5 is used for providing the mounting plate 5c2 with an elastic force away from the guide base 6d, the hinge seat one 5c6 is fixedly installed on the mounting bracket 15, the swing arm 5a is rotatably installed on the hinge seat one 5c6, a waist-shaped hole one is formed in the hinge seat one 5c6, and the transmission column one 5c3 is inserted into the waist-shaped hole one. When the swing arm 5a moves downward, the swing arm 5a will push the transmission column one 5c3 to slide outward along the waist-shaped hole one, at the same time, the transmission column one 5c3 will pull the limiting connecting plate 5c4 to move, so that the limiting connecting plate 5c4 pulls the pressing plate 5b to move outward through the guide column two 5c1 and the mounting plate 5c2, so that the pressing plate 5b can be separated from the bed net 10, and after the swing arm 5a is released, the pressing plate 5b is quickly reset and inserted into the top of the plurality of bed nets 10 through the elastic force of the reset spring 5c5, so as to ensure the positioning of the plurality of bed nets 10.

[0038] In order to drive the baffle 6a to move while the synchronous outer pulling mechanism 5c moves, ensure that the bed net 10 can be quickly positioned left and right in a short time when the pressing plate 4 moves downward, for this purpose, as shown in Figure 8 and Figure 9 As shown, the cross-direction pushing mechanism 6c includes rotating plate 6c1, hinge seat two 6c2, transmission column two 6c3 and transmission column three 6c4, the transmission column two 6c3 is fixedly connected with the connecting plate 6e, the transmission column three 6c4 is fixedly connected with the mounting plate 5c2, the hinge seat two 6c2 is fixedly installed on the guide base 6d, the rotating plate 6c1 is hingedly connected with the hinge seat two 6c2, the waist-shaped hole two is formed in the rotating plate 6c1 for the transmission column two 6c3 to slide, and the rotating plate 6c1. When the mounting plate 5c2 moves, the mounting plate 5c2 will push the rotating plate 6c1 to rotate along the hinge seat two 6c2 through the transmission column three 6c4, so that the rotating plate 6c1 pushes the transmission column two 6c3 to move horizontally, that is, the transmission column two 6c3 pushes the connecting plate 6e to move horizontally, so that the connecting plate 6e drives the baffle 6a to move horizontally, that is, the baffle 6a can quickly respond while the synchronous outer pulling mechanism 5c moves, and the time is shortened.

[0039] Because the model of the bed canopy 10 is different, the length and width of the bed canopy 10 after folding will also be different, but for the length direction change of the bed canopy 10, only the position of the horizontal moving sliding table 14 needs to be adjusted, and for the width direction change of the bed canopy 10, the final position of the movement of the baffle 6a and the pressing plate 5b needs to be changed, for this, as shown in Figure 7 the middle part of the guide column one 6b is provided with a threaded pipe 6f, the guide column one 6b is divided into left and right two sections along the threaded pipe 6f, and both sections of the guide column one 6b are engaged and connected with the connecting plate 6e, by rotating the threaded pipe 6f, the threaded pipe 6f can be engaged to lengthen or shorten the distance between the two sections of the guide column one 6b, that is, the length position of the baffle 6a can be changed, so that the final position of the movement of the baffle 6a is changed to adapt to the bed canopy 10 of different widths. At the same time, the mounting plate 5c2 is fixedly provided with a sleeve 5c7, the pressing plate 5b is inserted into the sleeve 5c7, and the top of the sleeve 5c7 is provided with a screw, the screw is engaged and mounted on the top of the sleeve 5c7, and the bottom of the screw passes through the sleeve 5c7 and abuts against the pressing plate 5b. When the position of the baffle 6a changes, the position of the pressing plate 5b also needs to be changed, because the width of the bed canopy 10 increases, when the pressing plate 5b moves outward to the final position, the pressing plate 5b still presses on the top of the bed canopy 10, so that the pressing plate 5b can be separated from the bed canopy 10 by this way. When adjusting the baffle 6a and the pressing plate 5b, it is best to adjust to the final position of the baffle 6a to ensure that the end of the pressing plate 5b is horizontal with the end of the baffle 6a.

[0040] As shown in Figure 10 the elastic pushing mechanism 4c includes an abutting spring 4c1, a guide column three 4c2, a blocking plate 4c3 and a guide plate 4c4, the guide plate 4c4 is fixedly installed on the pressing plate 4, the guide column three 4c2 is slidingly connected with the limiting connecting plate 5c4, the pushing block 4b is fixedly installed on one end of the guide column three 4c2, the blocking plate 4c3 is fixedly installed on the other end of the guide column three 4c2, and the abutting spring 4c1 is sleeved on the guide column three 4c2, and the abutting spring 4c1 is used to provide the pushing block 4b with an elastic force away from the guide plate 4c4. When the swing arm 5a cannot be continuously pushed and rotated, the pushing block 4b will be pushed, so that the abutting spring 4c1 is compressed, that is, the pushing block 4b can avoid the baffle 6a.

[0041] As shown in Figure 11 the swing arm 5a is fixedly provided with a block 5e, and the bottom of the avoiding rotating block 5d abuts against the block 5e. The block 5e blocks the avoiding rotating block 5d, so that the avoiding rotating block 5d can only rotate upward, but cannot rotate downward.

[0042] When in use, the clamping device 3 releases the clamping of the bed mat 10 to be transported when the bed mat 10 to be transported moves above the pressing arms of the bed mat pressing mechanism 5, and the bed mat 10 to be transported will fall on the pressing arms of the bed mat pressing mechanism 5, and then the horizontal moving slide 14 is reset, so that the pressing plate 4 moves above the bed mat 10 to be transported again, and then the downward pressing mechanism 11 presses the pressing plate 4 downward.

[0043] In the process of downward movement of the pressing plate 4, the pushing block 4b contacts with the avoiding rotating block 5d, and the bed mat pressing mechanism 5 is pushed to move, so that the pressing plate 5b is pulled out from the bed mat 10. When the avoiding rotating block 5d and the swing arm 5a cannot continue to rotate downward, the elastic pushing mechanism 4c is compressed, so that the pushing block 4b is separated from the avoiding rotating block 5d. When the pushing block 4b is separated from the avoiding rotating block 5d, the multi-layer bed mat 10 is compressed to the final position, and at the same time, the outward pulling mechanism 5c pushes the pressing plate 5b to extend, and the multi-layer bed mat 10 is limited and fixed. In the process of downward rotation of the swing arm 5a, the baffle 6a moves inward to limit and adjust the left and right sides of the bed mat 10.

Thus, if these modifications and variations of the present application belong to the scope of the claims of the present application and the equivalent technology, the present application also intends to include these modifications and variations.
